1. Significant Ideas:
1.1. Human carrying capacity is difficult to quantify
1.2. EF is a model that makes it possible to determine if humans are living within carrying capacity
2. Carrying Capacity
2.1. maximum number of a specie that can be sustainably supported by an area
2.2. difficulties of measuring human carrying capacity
2.2.1. human uses far greater resources than any animal (need to consider landmass as well)
2.2.2. substitution of resources if they run out as well
2.2.3. resource varies from country to country
2.2.4. developments in technology leads to changes in resource use. this mean we use less because machine becomes more efficient. or more because we are able to exploit resource better
2.3. EVS and Carrying Capacity
2.3.1. Technocentric -> technology can increase carrying capacity constantly
2.3.2. Ecocentric argues that it doesn't increase carrying capacity but only increase efficiency. And even if it does (food yield increase) -> the long term sustainability and efficiency decreases.
2.4. Objections
2.4.1. However, in the past, predictions has been made that 6 billion isn't sustainabile, however we have surpassed that. This suggest that the we have not reached the carrying capacity of human yet
3. Ecological footprints (EF)
3.1. Is impacted by EVS, productivity of food production, land use, and industry
3.1.1. eg: Netherlands vs USA
